if you are planning on keeping it a mech then post in the classifieds a wanted ad for an eclipse blade frame and hollowpoint 3 way.......without a doubt the best mech frame for a cocker and with a hollowpoint you can get your trigger pull down real short. the best version of the blade frame to look out for is the mk3 which has two adjustment screws on the actual trigger, this allows you to fine tune it even more.
there will be loads of people that have them kicking around from when they ebladed their markers so you should find waht you need for very little and see a good return for your cash.
a 2nd hand e1 frame is the other option....shouldnt be crazy money these days....if you can find someone selling the frame on its own.
but before you do anything to it draw a line in the sand....how much are you willing spend...dont go crazy or you will only find you are kicking yourself when you realize you have spent that much on it that you a, arnt going to see a return when you sell and b, could have bought a far better marker for the same cash
